Professional Schools Attended 1. The NASA Langley - ICASE Workshop on Instability and Transition, Hampton, VA,

May 15-June 9, 1989. 2. The NASA Langley - ICASE Workshop on Transition and Turbulence, Hampton, VA,

July 8-August 2, 1991. 3. The NATO Advanced Study Institute winter school on Ocean Modeling and Parameterization,

in Centre de Physique des Houches, Les Houches, France, January 20-30, 1998. Scientific / Technical Accomplishments • Developed and implemented numerous parameterizations and diagnostic packages in the

ocean component of the NCAR Community Climate System Model (CCSM). • Designed and developed many diagnostic tools for the analysis of the ocean model data for

community use. • Created the first version of the web-based ocean analysis package that has been used

extensively at NCAR. This tool makes model results available on the web to university collaborators, thus expediting dissemination of new solutions.

• Published over 50 refereed journal articles that are cited over 1600 times. • Continuous analysis and evaluation of the CCSM simulations. • Recently, focusing on mechanisms of multi-decadal variability in the simulated Atlantic

meridional overturning circulation and on decadal prediction with CCSM. The latter includes work on hindcast and DART assimilation initialization approaches for decadal prediction experiments.
